WebDec 9, 2024 · Velocity - how fast an object is travelling in a certain direction. Acceleration - how quickly it takes an object to reach a certain speed. Constant speed - an object moving at the same rate. Variable … Webpi = m1vi1. After the hit, the players tangle up and move with the same final velocity. Therefore, the final momentum, pf, must equal the combined mass of the two players multiplied by their final velocity, ( m1 + m2) vf, which gives you the following equation: ( m1 + m2) vf = m1vi1. Solving for vf gives you the equation for their final velocity:

3.6 Finding Velocity and Displacement from Acceleration

WebInstantaneous velocity is a vector quantity that includes both the speed and the direction in which the object is moving. Learn how to find an object’s instantaneous speed or velocity in three ways - by using calculus, by looking at the slope of a given point on a graph of an object’s rate vs. time, or by using kinematic formulas if the ... WebAverage speed is a scalar, so we do not include direction in the answer. We can check the reasonableness of the answer by estimating: 5 meters divided by 2 seconds is 2.5 m/s. Since 2.5 m/s is close to 2.9 m/s, the answer is reasonable. This is about the speed of a brisk walk, so it also makes sense. smart goal for finance 2023
